Definitions

• the invention relates to a camouflage fabric for covering a background during special effect shots, in particular for works in film and TV studios.
• camouflage textile allows for an easy installation, resistance to a mechanical wear, undemanding maintenance and a long operational life-time
• the known camouflage textiles are thin, their thickness not exceeding 2 mm.
• very important undesired features there should be mentioned a non-reversible and irregular change of a colour shade and the colour richness. The application is therefore limited to cases when their easy technical and economic accessibility have priority for the decision.
• camouflage textiles having a surface covered by a colour layer, usually with a higher content of non-transparent filler.
• Application of such camouflage textiles at present enables processing of special effect shots at the best currently available quality.
• the textile function is reduced to a carrier, as only its mechanical properties are utilised.
• Optical properties are provided for by applied colour and its shade.
• the solution applies a linen being single sided covered by a layer of a blue colour, the layer when disposed to a light having a temperature of 6000 °K featuring maximum reflectance for light of wave length in an interval 450 - 480 nm, the interval covering approx. 40 % of the amount of the reflected light.
• a textile having green colour characterised by maximum reflectance for light of wave length in an interval 510 - 560 nm, the interval covering approx. 40 % of the amount of the reflected light.
• This solution in practise comprise also simultaneous distribution of the colour itself. The said colour distribution allows on the one hand for small local corrections of the unified shade when necessary due to wear and/or dirtiness of the textile, on the other hand for covering joints.
• camouflage textiles wear away rather fast, even during ordinary works in a studio, mainly due to dust or routine maintenance.
• the wear is accompanied by uneven changes of optical properties, especially as regards a colour shade and a reflectance.
• coloured textiles particularly cloths, such changes are non-removable.
• the textiles covered by colour surface layer feature relatively large, flat and smooth areas showing rather high gloss, which cause parasite reflections of large amount of light, comprising even the very part of light spectrum which should be completely absorbed.
• Such a fact especially when a moving camera is in action, results in high demands not only upon cameramen and lighting engineers but also upon further processing, as a light reflex from a larger flat, optically unbroken surface, aiming in a single direction may completely damage taken shots.
• a camouflage textile comprising at least one optically effective textile layer
• the textile in accordance with the present invention comprising an optically effective textile layer having a thickness from 1,5 up to 12 mm, the layer consisting of a multiple of curved, poly-directionally oriented and in any plane linearly unaligned fibres having a thickness from 50 ⁇ m to 200 ⁇ m.
• the said fibres occupy from 1,5 % up to 20 % of the textile layer volume, while a space between the fibres occupies from 80 % up to 98,5 % of the said volume.
• the optically effective textile layer is at one surface furnished either with a reinforcing cloth having gaps the size of which is within the range of 0,5 up to 5 mm, or with a reinforcing knitting, showing gaps the size of which is within a range of 0,5 up to 15 mm. Still further in accordance with the invention the optically effective textile layer is at one surface provided with a reinforcing paint. In a preferred embodiment the optically effective textile layer is at one surface provided with an optically effective facial layer, the fibres of which occupy 1,5 - 5 % of the layer and the facial layer thickness covering from 10 % up to 100 % of the textile thickness.
• the camouflage fabric is of a uniform colour shade, preferably either the blue one, featuring a reflected light wave length of 450 nm up to 480 nm, or the green shade, featuring a reflected light wave length of 510 up to 560 nm,
• a uniform colour shade preferably either the blue one, featuring a reflected light wave length of 450 nm up to 480 nm, or the green shade, featuring a reflected light wave length of 510 up to 560 nm
• camouflage textile according to the invention shows no continuous, large, in space identically oriented shiny areas, producing parasitic reflexes. Similar to known solutions the applied colour shade then determines in which part of a colour spectrum is the textile reflectance the highest one.
• the camouflage textile according to the invention is resistant against wear, namely against dirt, including dirt tracked up by walking and standard dustiness, as dirt and first of all dust penetrate down to varies depths of the textile layer a do not form areas influencing optical properties.
• dustiness or dirtiness of the textile can be without any problems removed by standard vacuum cleaner or by homogenisation of the textile surface by a mere quick brushing.
• the camouflage textile comprise up to three layers, namely additional optically active, sparse facial layer, the fibres of which occup 1 ,5 % up to 5 % of the layer volume while the rest 95 % up to 98,5 % of the volume is a free space, above described optically active basic layer and an underside, reinforcing layer.
• the reinforcing layer may be formed by a knitting; grid, netting, sparse cloth, felt, reinforcing paint-over, even by a foam layer. Thickness of the facial layer includes from 10 % up to 100 % of the basic layer, the reinforcing layer is thinner than 2 mm.
• the optically active layer is preferably made of polyester, especially from matt, cut fibres of a recycled material.
• the reinforcing knitting or sparse cloth is preferably made of cotton.
• Reinforcing paint-over or foam layer is preferably made of permanently resilient material, based e.g. on caoutchouc. Individual layers, especially the facial and the basic ones may merge one into the other with a boundary between them being invisible.
• camouflage textile comprised one non-woven layer having a thickness of 7,5 up to 8,0 mm and consisting of poly-directionally oriented, multi-curved, i.e. in any plane lineary unaligned fibres.
• the fibres were cut ones from a recycled material, the fibres having a thickness within the range of 90 ⁇ m up to 200 ⁇ m and being in a matt modification
• the fibres occupied from 5 % up to 10 % of the textile layer volume while a space between the fibres occupied from 90 % up to 95 % of the said volume.
• the said fibres were coloured with a blue dye having maximum reflectance of the light of 465 nm wave length.
• This embodiment of the textile has shown excellent results when used as a cover of vertical surfaces, being partially extended upon floor not used for any activities.
• a reinforced camouflage textile comprising two layers.
• the first one an 8 mm thick, non-woven layer of poly-directionally oriented, multi-curved, polyamide fibres had a thickness within the range of 180 ⁇ m up to 200 ⁇ m and was in a matt modification the fibres occupied from 5 % up to 15 % of the layer volume, the space between the fibres occupying from 85 % up to 95 % of the said volume.
• the said fibres were coloured with a blue dye having maximum reflectance for the light of 465 nm wave length.
• the second, underside layer was prepared as a foam layer of a thickness in the range from 0,5 up to 1 mm. This embodiment of the textile has shown good results when used as a cover of large vertical surfaces, being partially extended upon floor under a low load.
• the first, facial, 2 mm thick, non-woven layer of poly-directionally oriented, multi-curved, polyamide fibres had a thickness within the range of 50 ⁇ m up to 100 ⁇ m and was in a matt modification
• the fibres occupied 2 % of the layer volume with a space between the fibres occupying 95 % of the said volume.
• the said fibres were coloured with a blue dye having maximum reflectance for the light of 465 nm wave length.
• the facial layer merged into a 5 mm thick basic layer, consisting of poly-directionally oriented, multi-curved, polyester cut fibres from a recycled material, having a thickness within the range of 50 ⁇ m up to 100 ⁇ m and being in a matt modification
• the fibres occupied from 3 % up to 8 % of the layer volume, the space between the fibres occupying from 92 % up to 97 % of the said volume.
• the said fibres were coloured with a green dye having maximum reflectance for the light of 535 nm wave length.
• the third, underside layer was composed of reinforcing knitting in a form of a net having a mesh size 5 x 5 mm and the same colour shade as the other two layers.
• the third layer had been fused with the basic layer.
• This textile has shown very good utility properties being applied as a cover of large vertical surfaces and partially extended upon floor under low load.
• the first one 4 up to 6 mm thick, combed layer of poly-directionally oriented, multi-curved, wool fibres had a thickness within the range of 50 ⁇ m the fibres occupying 3 - 5 % of the layer volume with a space between the fibres occupying 95 - 97 % of the said volume.
• the first layer merged into a second one, 1 - 2 mm thick woven layer, consisting again of poly-directionally oriented, multi-curved, wool fibres.
• the second layer merged into the third layer being similar to the first layer.
• the textile was coloured with a green dye having maximum reflectance for the light of 535 nm wave length. This textile has shown very good utility properties being utilised as a wall cover and other applications like that but is suitable also for clothing purposes. This textile may be used double-sided.
• the camouflage textile according to the present invention is designed for film or TV industry, for a camouflage of a background by special effect shots taken either in an interior or in an exterior, or for production of audiovisual or photographic works
